## Summary

Mirendil has released Fern 0.1, its first AI model, a from-scratch coding model with a context window of up to 10M tokens, available only through early access. On RULER single-needle retrieval it scores 100% at every length from 32K to 10M tokens, but it scores 6.1% on Terminal Bench 4.0 against 66.4% for Claude Opus 5.5 in Mirendil's own table.
